Where would I enter after tax dollars contributed to an employer provided 401k? I'd like to max out my contribution this year.

Employee deferrals to an employer provided 401(k) retirement account can only be made on or before the last day of the calendar year, eg 12/31/2022 for tax year 2022.

Your deferrals are located on your W-2 in box 12 with a code of D.

After-tax money contributed to the 401(k) would only be entered in the section for determining any Retirement Savings Contributions Credit, but someone making after-tax contributions to a 401(k) probably doesn't qualify for that credit.

Although after-tax contributions to the traditional 401(k) account are different from elective deferrals, it's unlikely that your employer would accept an after-tax contribution made in 2023 as a contribution for 2022.  Allowing that would make a mess of anti-discrimination testing.

To be clear, you do not get a deduction for after-tax contributions made to a 401(k).

Thanks!  I actually was researching the subject on other sites and found exactly as you stated.  Appreciate the response.  Now I know why there's no place to enter it....
