You will be notified by either text or email, whichever you chose in the Filing step.
Please note:
1. You are filing a 1040 tax return, not a W-2. The W-2 is just one of the documents attached to the 1040.
2. You are filing the 1040 with the IRS (Internal Revenue Service), not with the Social Security Administration.
3. At the end of the Filing step, you should have been asked how you wanted to be notified if your 1040 filing was accepted or rejected (text or email). I imagine that if you try to re-enter your return in TurboTax that you will be told then, too.
NOTE: e-filing does not begin until January 17, 2025, so it will be a week or more before you hear anything.
