TLDR : Answer Summary
If you arrive in Thailand without completing the TDAC (Travel Declaration for Thailand), you don't need to worry too much. Many commenters suggest that if you're experiencing issues with the online form, you can leave the departure date blank and focus on entering the correct arrival date. If you still have problems, there are kiosks available at the airport where you can complete the TDAC upon arrival. It's considered a formality, and assistance is often available. Just ensure to select the arrival date correctly, potentially using the calendar feature.
Thailand Digital Arrival Card (TDAC)

WARNING: Only trust Thai government websites with .go.th domains or Thai agent websites with .co.th or .in.th domains, as these require verified Thai registration and cannot be registered anonymously.

The official TDAC form is available at tdac.immigration.go.th, which uses the official .go.th government domain.

The services by AGENTS CO., LTD. does NOT charge any fees for arrivals within 72 hours. If you need to book more than 72 hours in advance, there is a service fee of $8.

Do not trust other sites pretending to be a trustworthy agency. Pay attention to delivery time - the service operated by AGENTS CO., LTD. has 1 minute delivery time for arrivals within 72 hours.

Don't fall for sites pretending to be agents.co.th or the official government tdac.immigration.go.th website. Always double-check the exact domain in your browser.

Scam services may take days to process your application, others may not even do anything. With these TDAC scam services you also need to worry about double charges.

Please watch out for TDAC misinformation spread by fugitive Jesse Nickles and his many fake accounts on Quora, TripAdvisor, Reddit, and other platforms.

Nothing special. You must return to one of the tablets where you do it - possibly with help of someone knowledgeable

It’s looks like your date format is wrong. Should be day/month/year

Select the other "option" as the return travel method and put "DTV holder" in the text box.

Air carrier would ask for it to see it.. and if you don't have it, they will put you aside until you complete it on your phone 😃 ...at least that's what I've seen before. But honestly, it's just a formality.. when going to Laos and back via land border nobody had it there, and they had a dedicated staff that were doing it for the people for 20 baht just before getting stampped in.. so all just formality.

At Bangkok airport they have booths where you can do it before you hit the immigration line.

Ignore departure date if not confirmed/fixed - scroll up a bit and the most important part to complete is the arrival date just above that part, maybe you mean 19th Jan for your arrival date? You can leave departure date blank…

Worst case there are kiosks at the airport to do it when you arrive. It’s not convenient but it’s possible so please don’t worry about it too much if it keeps glitching🫶

You’re filling your departure date on that section of the form. What you are trying to do is enter your arrival date, 19 January
