I was reassessed for my 2020 Self Employed Return - How do I get the data from CRA updated into my 2020 TurboTax Online?

I was reassessed for my 2020 Self-Employed Return - How do I get the data from CRA updated into my 2020 TurboTax Online?

I was told that I have to carry forward the amount, BUT if it's not showing in my 2020 Turbotax filing, then it won't grab the carry forward.

I don't want to redo the whole thing from scratch, if there is a way to download from my CRA account. 

Thanks All!!
