Has the issue with the efiling after 401k excessive distribution been fixed? Mine still asks to review my W2 and I can't continue.
It was just announced that an update is currently planned for April 12th, 2019 to resolve this e-filing issue.
You may still see a warning about the excess contribution, but you should be able to e-file. You can check out thisTurboTax FAQ for more information: Excess 401(k) Contribution Preventing E-filing.
