Very sorry for your loss.
It is not clear from your post that your BF claimed you. It should be pretty easy to ask him if he did so. If your BF did not claim you as a dependent, and cannot claim you for the reasons explained in a previous reply, then it is also possible that someone else used your Social Security number on a tax return---either by mistake or on purpose. If your SSN has been put into the system already, then you cannot e-file a 2020 return.
If someone else CAN claim you as a dependent then you need to say in My Info that you can be claimed.

If you cannot be claimed as anyone else's dependent and need to file your own tax return, then file on paper. Print, sign and mail your return. The IRS will sort it out. Expect it to take awhile for them to process your return, since mailed returns are taking months to be processed. Use a mailing service like certified mail to track it so you will know the IRS received your return.
Federal and state returns must be in separate envelopes and they are mailed to different addresses. Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.
