I didn't file my son's return for 2022 because he didn't work but one month. I am trying to add it to his 2023 return, how can I do this or can you do this?

I'm trying to see basically can I combine 2022 and 2023 on one return for this 2023 return.

NO,  you cannot add 2022 income to a 2023 tax return.   Only 2023 income goes on a 2023 return.

You say he worked for a month in 2022. Explain if he has a W-2 with anything in box 2 or 17; or if he had self-employment income of over $400.

No, you can't add a 2022 tax document to a 2023 tax return.

Each tax year has to be filed separately.

You can only use TurboTax Online to file the 2023 tax return.
