Did you use the link above to see if it was Accepted? Sounds like you didn't finish filing it. You only have today to efile. Try Efiling again.
Click on Add a State to let you back into your return.
From Tax Home (the first screen you see after you sign in), scroll down to Your tax returns & documents. You may have to select Show to open the drop down.
Select 2021, and then select Add a State (you're not actually adding a state, this is just the workaround). Go all the way through the File tab, through the 3 steps and hit the big orange button to submit it.
If it thinks you mailed it you can try to switch to efile
