My EFile says transmission failed due to w-2 data import. I didn’t use the data import function. I called TurboTax and it said it’s an issue on their end and the wait time to talk to tech s

Same here. Most frustrating part is that I tried to re-import, that failed, and then I manually entered all 4 w2s we had and still got the transmission failed. This was after they happily collected my payment.....

If you imported a W-2, some pieces of information may be missing or were inaccurately entered during the data import process. To ensure your 2019 TurboTax return is accurate, please delete ALL your W-2s and then re-import them into your return before submitting your return to the IRS.

Do not e-file your return before Thursday, January 30, 11:59pm PST.

Follow these steps to delete and re-import your W-2s.
