401k contribution limit wrong in turbotax home and business 2023

[dmertz]

There is no such bug.  You are confusing a 401(k) with an IRA.  A 401(k) is not an IRA.  Nothing about your 401(k) contributions is to be entered under Deductions & Credits.  Enter amounts shown in box 12 of your W-2 only in box 12 of TurboTax's W-2 form, nowhere else in TurboTax.
