The 2018 Premier edition program say the W-2G Summary Elective deferrals - SP $37000 is more than the allowed $18500 for a 401k plan. The program is wrong because the W-2G summary is the combination from a 401k and a 403b on separate W2s where 12a is D and 12a is E respectively. That is the wrong limited when combined. The program is wrong.
TurboTax enforces the correct section 402(g) limit of $18,500 for an individual's 401(k) and 403(b) contributions combined. For an individual under age 50 in 2018, the limit of the sum of that individual's Form W-2 box 12 entries (from all employers) with codes D, E, F, S, AA, and BB are not permitted to exceed $18,500.
An individual under age 50 who has one Form W- with a box 12 code D amount of $18,500 and another Form W-2 with a box 12 code E amount of $18,500 has exceeded by $18,500 the amount that that individual is permitted to defer to these plans.
This error prevents me from e-filing. This was not the chase on 2017, and 2016.
