How can i add two more tax returns because i three jobs last year.

You can add them now if you have NOT e-filed.

Every 2023 W-2 that you received must be reported on your 2023 tax return, even if they are for small amounts.  Remember that each one of those W-2’s has your Social Security number on it, and that income was reported to the IRS by the employer.  You do not want to get in trouble with the IRS for under-reporting your income or have your refund delayed by having missing income.

ALL of your W-2’s must be entered on the SAME tax return.  

Go to Federal>Wages & Income to enter a W-2.

After you enter the first one, you click Add Another W-2.

You do Not add tax returns for each W-2 you received.  You enter ALL the W-2's for tax year 2023 on only ONE tax return.

When you have finished entering one W-2 the program will ask you if you have another W-2 to enter, answer Yes.

Assuming that you mean you need to add more Forms W-2 to a tax return you haven't filed yet, it's fairly straightforward. 

See the TurboTax Help article Where do I add or enter a second W-2? for guidance.
