What if my bonus went directly into my 401K do I still claim it on my 2021 taxes?

[JulieS]

If your bonus was paid by your employer and put into your 401(k), both of those things are listed on your W2 form. All you need to do is enter your W2, including the box 12 entries. 

[Opus 17]

Just enter your W-2.

Do not enter your 401(k) in the section for IRA contributions.  An IRA is a private, separate account and is covered by different laws than the 401(k), even through they have some similarities.  Your 401(k) is only reported from your W-2.
