Was my federal submitted

This is mainly a user community forum, so we won't know anything specific about your return.  We can tell you some things to check, however.

Did you choose to efile, or did you choose to print, sign, and mail?

If you efiled, did you go through all the screens in the FILE section, until you got to the final screen and clicked a big orange "Transmit My Returns Now" button?

If so, have you received an email that the return was transmitted?  (check spam/junk folders and other email accounts, too).

When you log back into your online account, what do you see displayed there?   Do you see a "return status", and does it say "pending."

You can also check the efile status with this tool:
