How can the retained earnings of prior year be adapted to current year

It's my first time using turbotax incorporated for NPO. I put a data current year and prior year to my Income Statement Information, and as I was checking my Balance Sheet Information, I have found out that in the Retained earnings/deficit section, the "Retained earnings/deficit current year" didn't affect on the current year retained earnings/deficit even though I have put the data from the prior year.
