I get an error: "The amount you designate for transfer to an RRSP/PRPP cannot be greater than the eligible income reported for transfer". How do I fix this?

I contributed my bonus to my RRSP in February 2019, so it is within the 60 days. I did the same thing last year. This year, when doing taxes, I attempted to put it into the designated transfer but an error came up saying it could not be higher than the transfer. I read here that there should be a box 60 on my T4 from last year but that also is not there (from doing the same thing last year). Where should I put the RRSP contributions I did last month?
