NY State filing asked for old return information?

I am trying to complete my NY state tax filing. I was asked at some point to input my 2018 tax total and credits total. I accidentally input the incorrect information. I want to correct this but I can't seem to find the section where I'm able to input this information. Is there a way to go back to this section so I can correct it? I've tried going through my state filing several times but I can't find it. I have not filed yet.
