2018 tax return

We cannot see your tax return or your account and we do not know what the IRS said in the letter they sent to you.  TurboTax does not get any information after you file your tax return.  It sounds like they are saying you had some income that you entered incorrectly or did not enter at all.  The IRS matches up the information you enter and the income information reported by employers and financial institutions.  Better take a look at your 2018 return and see if what you entered about your Edward Jones account was correct.

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.
