I have the same issue - the form looks correct and like you I only have numbers in A1, B, C (and also in I).
I had the same issue with Federal Tax, but I was able to "Skip Error" and TurboTax allowed me to file anyway, but TT will not Netfile Qc.
There is nothing here to fix and no instructions in TT - it just says "Fix" which then brings me to the T5/Releve 3 forms which seem correct to me.
