What do you mean by "received a paycheck in Jan for Dec"?

Only employees receive paychecks. 

Did you receive Self-Employment income in January?   

I worked through the end of Dec and was paid for that work in January, thus having to claim that income for 2020. That is my self-employment income for Jan. I became a w-2 employee in 2020 and so don't have other self employed income to report. But it keeps cueing me to report more.

Is this the final year you have that self-employment income?  If so, be sure to select that you ended the business in 2020 as this may help.

You can review your input in the federal interview section of the program as follows:

3. Select Edit on the next screen
4. Under the screen titled Here's your business info, select Edit to the right of General info
5. Select Edit under Stopped work in 2020 and change your answer to yes if it isn't already.
6. Proceed through the screens to enter your information regarding your business. If you do not have any additional income or expenses to report, you do not need to enter anything else.
