I also am having the same exact problem but when importing stock transactions from Charles Schwab. After going through the steps to import transactions I can see the connection between TurboTax and Schwab. Then there is a message that says "Success. We got your Tax Data. You can now return to TurboTax". Next there is a pop up windows that says "Do you want to allow this page to open "Turbotax 2022 App? I can then click on "Cancel" or "Allow". I click on "Allow" and the next thing message I see I am back in TurboTax and the Message says "Import Unsuccessful". No one from TurboTax has been able to solve this problem. This is really aggravating.
