Can anyone help? I have code d22 along with code d in box 12. How do I enter both? I only see the D option. When I try to enter both, turbo tax is making me delete one

Is it DD?  DD – Code DD includes cost of employer-sponsored health coverage.   D -- Code D is for your 401K contributions. 

Nope. This is what it is. 

You should contact your employer's HR Department to find out what this code and amount are for; perhaps they inputted it incorrectly.

D 22 is a 401K contribution for 2022.  You can add both code D together and enter the total.
