New - If you filed and claimed the Recovery rebate credit but already received the full Stimulus payments you can call it back and update your return so it isn't delayed

https://ttlc.intuit.com/community/tax-topics/help/i-ve-already-claimed-the-recovery-rebate-credit-ho...

If you haven't e-filed or mailed your income tax, search for stimulus and select the jump-to link at the top of the search results to return back to the section. Enter your updated info and Continue. 

If you've already e-filed your income tax return, see I've already claimed the Recovery Rebate Credit. How can I review and update my 2020 tax return?

Note: Your stimulus payment isn’t taxable. It won’t reduce your refund or increase what you owe when you file your taxes this year. It’s also not considered income, so it won’t affect your eligibility for any federal government assistance or benefits. To read the entire TurboTax FAQ, click here. 

So even though it has not been transmitted to the IRS and accepted there is no way for it to be corrected now?  Also what about the additional W2 I need to ad.  I filled out the form to correct the stimulus mistake, will it allow me to add the additional W2 at this time?

thanks,

Mike

If you want to review and update your 2020 return, please enter your information here by February 6, to have your 2020 tax return sent back to you.  You will then receive an email from TurboTax on February 8, letting you know that your return is available and providing you with detailed instructions on how to review, update and re-file your tax return without the Recovery Rebate Credit.
