Should I check the got a raise/bonus button for a temporary raise? I was made interim supervisor of my crew on September 25th last year.

Yes, you can. Selecting that button will prompt the program to ask you questions about your raise/bonus. You would also encounter these questions as you walk through the program in Guide Me whether you answered that intro question or not.

How do I go back to that button once I've started working on my taxes?

@awa1010 Unfortunately, you can't get back to those initial screens once you've started your return; however, that doesn't affect your tax return.

If you received a a raise/bonus, just enter your reporting document as you normally would.

If you received a 1099-Misc or 1099-NEC, type '1099-misc' or '1099-NEC' in the Search area, then click on 'Jump to 1099-xxx' to enter. 

This income is taxed as regular income.
