Someone changed my EFIN and I cant file 2020 tax returns how do I fix it?

IRS changed your EFIN?

It got changed in intuit's records?

The homeless guy down in the park hacked your computer and scrambled it?

Perhaps a little more light on the subject will allow someone to stop guessing and give you some ideas.
