Are you asking if you did file your return OR if you claimed yourself on it?
Did you go all the way through the File tab, through the 3 steps and hit the big orange Transmit Returns Now button?
You might be able to check your efile status here

When you efile you get back 2 emails. The first email only confirms the transmission. The second email says if the IRS (or state) Accepted or Rejected your efile.
Even if Turbo Tax lets you submit your return they will just hold all the returns until the IRS opens filing on Feb 12, 2021. So there is no hurry. And a lot of people who file early find out they have to amend later like when they get their actual W2 and 1099 forms. Or they get more forms than they were expecting.
