QC & ON - T4 but no R1 - Entry Mismatch

I get the following NETFILE error message, in turn preventing me from using CRA's NETFILE service:

"Your Relevé 1 and T4 entries don't match. The total of boxes B-A, B-B, B1, and B-2 of your Relevé 1 must equal the total of boxes 16, 16A, 17, and 17A of your T4."

 

I changed job in 2025 - the first job R1-T4 numbers are an exact match. 

I live in Quebec, but province of employment for the new job is Ontario. I received a T4 and no R1.
