5 E-file Limit

I installed TurboTax 2023 using my sister's download (who lives in another state).  When I tried e-filing, TurboTax explained that the limit of 5 e-files had already been reached - which I also confirmed with my sister.  So I then uninstalled it, purchased a new copy using my own Intuit email address and installed this new version.  I still get the same message the my limit of 5 e-files have been reached, however, even though I am using a new email address on a computer that has never submitted an e-file (and in a completely different state).  Are there still files from the previous version that need to be deleted?  Anyone else have this problem?
