Summary discrepancy of 2021 PA taxes owed

Been encountering several apparent bugs in 2021 TurboTax Premier for Mac which I have been able to work around but this one is the most concerning. After 2 completely separate run-throughs of my 2021 fed & PA state taxes, TurboTax for Mac consistently comes up with a discrepancy for what I owe PA. Within the state return, it shows I owe a substantial amount (which should be correct). Yet each time TurboTax takes me back to the main program, while the app's summary screen shows the correct amount for federal taxes owed, it shows I owe "$0" to PA! However, the worksheets behind the "$0 owed" do show the correct PA taxes owed. I'm concerned about filing. Until this discrepancy is resolved, how do I know that the correct tax info will be electronically transmitted to PA? Anyone else having this problem?
