I filled my taxes already and irs accepted and sent me my return. Will it affect it if I amend and send my other w2

When you amend your tax return to add another W-2 that you omitted, you might get an additional refund, or you might have to pay more tax. It depends on how much income is on the added W-2, how much tax was withheld, the amount of income on your original tax return, and other factors. When you prepare your amended return it will tell you whether you will get an additional refund or have a payment due.

In the future you should not file your tax return until you have entered all your W-2s.

How do I amend my 2019 TurboTax Online return?

An amended return has to be filed on a special form, Form 1040X. It cannot be e-filed. You have to print it, sign it, and file it by mail. It takes the IRS up to 16 weeks to process an amended return.

Don't file the amended return until your first return has been accepted and you have received the original refund.

If you will owe additional tax, or will have to pay back part of your refund, you should file the amended return before April 15 to avoid possible penalties and interest.
