I rec'd a C2000 notice from the IRS for tax year 2022. I neglected to enter our SS income for which an adjustment of $2000 including interest. Why wasn't this noticed?

This would seem to be a glaring mistake that TurboTax should have caught.  I'm going to need an explanation.

TurboTax has no way to know that you have received SS benefits.

The program shows you all the types of income that you would have received during the year.  If you choose not to review those types of income while you were in the Wages & Income section, that is on you.

Additionally, it is your responsibility to review your tax return before filing.  If you did not review the return then the fault for not reporting the SS benefits is yours.

TurboTax cannot see the papers on your desk. It has to rely on you to enter all of your income. If you had income that you did not enter, there is no way for TurboTax to know that.

Your personal AGI will know your finances, watch your tax return being prepared  and remind you that you left out your SS income.

We're not there yet.
