For box 14 The code listed is S. I’ve completed my tax return and turbo tax doesn’t like it and won’t clear final review. It’s looking for me to correct it.

Box 14 or 12?  See this employee answer for W2 code S

A TurboTax employee posted this:

. On January 8, 2024 (i.e., just two weeks ago) the IRS released a notice describing many changes required to implement the Secure Act 2.0 - I believe that this is what "We're updating how SEP and simple plan contributions are reported on the tax return based on new guidance from the IRS." is referring to.

Indeed, Section 601 of the Secure Act 2.0 refers specifically to Simple and SEP Roth IRAs. Code S in box 12 refers to how to handle a SIMPLE plan.

These last minute IRS (and law) changes inescapably cause delays on the part of TurboTax and other tax processors. 

It will take time for TurboTax to understand all the ramifications of this IRS Notice and then code and test the changes. The IRS is not open for filing until January 29th so you have some time to wait.

if it is box 14 ask your employer since there aren't any standard codes for that box. Tell us what it's for and we may be able to help
