Get your taxes done using TurboTax

That usually fixes it.  Usually it is due to a preference or Applications Support file.

Beyond that if you switch to (or create) another Administrator User account and install TurboTax in that account and it works correctly then there is something wrong with the first User account.    Troubleshooting an internal Mac User account issue is beyond the scope of this forum and should be referred to Apple support.
