If this doesn't work or you selected Deny, remove Intuit session tokens stored in the Keychain.
Navigate to /Applications/Utilities directory and launch the Keychain Access application. Type intuit id in the search box located at top right corner.
If you notice any search results for Intuit ID and Kind as application password, delete them.
Check this also:
In Finder, select the Go menu at top and then select Go to Folder.... Type ~/Library/Application Support and select Go. Select the TurboTax * 20XX directory and delete AuthorizationClientContext.plist, if present.
I shut down TurboTax and brought back up, but the suggestion I received was to reboot, shutting down worked for me.
Restart (if necessary) your computer and try importing again from ItsDeductible in TurboTax.
