My 401K contributions are being added twice in the software?

[dgavitt1]

My 401K contributions are being added twice in the calculations even though my W2 is correct. The software thinks that I over contributed by $31K.

Your 401(k) contributions are on the W-2 you received from your employer, in box 12 with a code of D.  Those contributions are NOT entered anywhere else on your tax return.

If you entered the 401(k) contributions in the section for reporting IRA contributions, delete those entries.

It seems doubtful that mistakenly entering the 401(k) contribution as an IRA contribution would be the cause since, unless the amount in box 1 of the W-2 was zero, the excess IRA contribution calculated would be less than $31,000.  It seems more likely that a second W-2 showing a $31,000 401(k) contribution has been entered, the code-D item in box 12 has been entered twice, or there is a $31,000 code-AA item in box 12 of the W-2 in addition to the code-D item. (The sum of employee deferrals to all of the individual's 401(k), 403(b) and federal TSP plans is not permitted to exceed $31,000).
