Did you e-file already? If you have not e-filed you can go to Federal>Wages & Income and add your other W-2's. ALL of your 2023 W-2's are supposed to go on the same tax return. After you enter the first one, you click ADD W-2 and keep going until all of them have been entered.
If you already e-filed and did not put all of your income on the tax return, you will have to wait for the return to be fully processed and then amend it to enter the rest of your income.
