My accountant sent back their file with the accountant changes made on the file(we'll call F1), all I needed to do was upload the file.

But the option to do so was not there(it was in light gray and unavailable). I believe because I had removed restrictions some time ago and forgot..

Unfortunately, I then sent another accountants file thinking I could then upload the F1. However now when I try to open F1 it says the file can not be opened.

Is there any way my accountant and combine F1 with the second accountants copy I sent? With out having to manually change all of the updates made by the accountant for a second time?

Thank you!
