Total Non-Refundable Tax Credits

[canusatrini]

Filed my 2021 tax several weeks ago, received return of approximately $8,000.00 as I withdraw extra taxes so as not to ever have to pay CRA. My 2021 Taxes were reassessed and CRA advised I owe $830.00 on 04-27-2022 and I paid that amount on 04-28-2022. CRA indicated the difference was in Total NonRefundable Tax Credits.

What I would like to understand is how and where I made this error in Turbo Tax so I don't repeat the same thing in 2022. I need for someone to tell me whether I selected the wrong box or what I chose is not allowed and where it is on Turbo Tax.

This has not happened in any of my previous taxes.
