After you file

@Outlaw_865 If you are referring to your 2021 tax refund, that was not an "audit."   Not all changes made to your tax return by the IRS are the result of an "audit."   However, if the IRS found some sort of mistake and reduced your refund after a review, or after finding that you owed back taxes, child support or made some sort of data entry error, then your refund could be reduced and you would receive a letter from the IRS.   Did they send  a letter for 2021?   Or are you referring to some earlier tax year for which you really were audited?

I RECEIVED A LETTER FROM THE IRS/STATE

TurboTax does not receive any information from the IRS or your state after your return was filed, so no one at TurboTax knows about a letter you received from the IRS or the state.

(what the letters from the IRS mean)
