I have a 401k over contribution for TY2018. I've corrected this, and have 1099Rs to show for it, but can't e-file because my W2s add to over 18500. please help.

TurboTax is aware of the e-filing issue that you are having and is currently working on a solution. An update to fix the issue is expected to be released around 4/5/2019.  

Be sure to sign up for updates to be alerted as soon as there is a solution.  If you do not want to wait for an update, you have the option to paper file your tax returns as this is only an e-filing issue.

You can check out this recently added TurboTax FAQ for more information: Excess 401(k) Contribution Preventing E-filing.

If you haven't done so already, you should click here and follow these instructions to include your excess deferral as wages on your return: Including excess 401(k) contribution on Line 1 of Form 1040.
