My Accountant hasn't finished my taxes

My Accountant still has not completed my taxes. I provided her my tax documents a month ago. In the past, we had in-person appointments where she completed my taxes while I was there (in about 2 hours). This year, she wanted to do everything without a meeting - upload it to a secure website and she will let me know if there are questions.

This doesn't seem to be working. She has never reached out to me. When I contact her for an update she says she is 90% done or that she is currently working on it. My taxes are not complicated and my situation hasn't change this year so should be the same effort as last year.

I have never filed a late return. Do I need to file my own extension? I don't know if I will owe or not -- I think not -- but I won't know for sure until she is done and I don't feel like I can count on her.

To me this is unprofessional and unacceptable. If she would proactively reach out, I would be understanding, but she is not sharing any information with me.

What should I do to protect myself?

Thank you.
