can I amend a return filed with another accountant?

Greetings,

I used an outside accountant to file my 2021 return. This accountant marked me as single/0 instead of HoH.  I want to amend my return using turbotax and in general leave no longer use that accountant in the future. Is there a way to amend my return using TurboTax? I tried looking up the information and the only amend options are for taxes already filed through TT.

Thank you
