I filed taxes for 2019 but they asked me the AGI of 2018, and I put the wrong number. How can I change it?

Your tax return will be rejected by the IRS and you can then enter the correct 2018 AGI in the same place you entered the wrong number.

My question to u is I made a mistake by hitting YES to the question that asked if I had filed for my 2018 returns....WHICH I WAS SUPPOSED 2 HIT 'NO' BECAUSE I DIDN'T CLAIM AT ALL FOR LAST YEARS INCOME TAX RETURNS AT ALL. WASN'T  WORTH THE TIME BUT ONCE I MOVED ON WITH ME HITTING THE YES BUTTON THEN I WAS ASKED WHAT MY AGI WAS FOR 2018 WAS,.,IN•WITCH I GOT CONFUSED AND ACCIDENTALLY TYPED IN A TOTAL AGI AMOUNT THAT WASN'T FROM 2018's RETURNS ,IT WAS 2017's.. and now I've bin REGECTED FROM BOTH MY FEDERAL AND STATES TAX RETURNS. Am I able to go back into my turbo tax account and fix my answer 2 even claiming for year 2018 by mistake so I can just switch my response to NO I did NOT CLAIM 2018's,,,JUST 2017's  & now 2019 returns

Your tax return will be rejected for an incorrect AGI.   You will then correct your return to add the correct AGI from your 2018 tax return and refile your return.

If you need a copy of your 2018 tax return follow these steps:

1. Sign in to TurboTax making sure you're using the same TurboTax account (with the same username) as in prior years.  

2. Select Documents from the navigation.  

3. Use the drop-down menu at the top of the screen to choose the tax year want.

4. Then select Download PDF.

When you are in the efile section you will be asked to enter your AGI to verify your identity.
