I'm entering my home office expenses (vs. using the standard) and the boxes are all for 2020. Should I be going back? Why are they not 2021 boxes?

When I'm entering in home office information (mortgage interest, utilities, etc) the box to enter is labeled 2020. It has 2019 in, and then box is 2020 (not 2021). I'm not sure if I should go back? Enter 2021 there anyway? Not sure if this is a bug/glitch?
