What steps should I take for my DTV visa application from the U.S. while still in Thailand?

Heading back home in a couple of weeks. I plan to apply for the DTV visa while I’m there.

Is there anything I should take care of now while I’m still in Thailand documents, paperwork, or parts of the process or can everything be handled from the U.S.?

Also, for showing income: I’m paid two ways from the same company, which I’m part owner of. First, I receive a regular monthly salary. Second, I receive monthly distributions that vary a lot. Both are well above the required amount, the salary alone already meets the requirement.

Should I avoid mentioning the distributions to prevent confusion, or is it better to show the higher total income even if the salary alone qualifies?

Thanks in advance.
