ah, I see. That's so they know whether to give you the day 5 atk. I wouldn't worry too much about that. You can always pick one up at a 7-11, although I hear most people have trouble uploading the results anyway so not sure how officious they're being with it. Have you arrived already? I'm sure they'll give you one anyway in arrival if you ask, regardless of what you put on the application
The Thai pass is only required for entry into the country so I'm not sure what you mean when you say you only got it for 5 days. The entry stamp on your passport will tell you how long you can stay for. If you came in visa exempt that would normally be 30 days
