TurboTax won't let me efile because my two W-2s 401k amounts are more than the $18,500 max. I handled that through an excess deferral 1099-R form. Do I have to mail file?

This was not fixed in 4/5 update.

Looks like it is 4/12 now: <a rel="nofollow" target="_blank" href="https://ttlc.intuit.com/questions/4698409-excess-401-k-contribution-preventing-e-file">https://ttlc....>

The reason you are having to file by mail is that your tax return needs an explanatory statement and that cannot be e-filed.  But, you can manually add those wages back without an amended W-2.  You say you already handled it through a 1099-R.   Please check your 1099-R and see the answers below to make sure you have reported it correctly.  Note the dates are from previous years, so adjust accordingly.
