You don't enter the money you paid. What you enter is the expenses incurred.
After answering no to having a 1098-T, answer yes to qualifying for an exception (that gets you to the entry screens).
Room & board is only a qualified expense for a 529/ESA/Q TP plan distribution. Therefore, TurboTax (TT) will not give you a place to enter R&B unless you earlier told it that you took a distribution from a 529/ESA/QTP (in the 1099-Q section)..
To get the screen to enter Room & Board, answer yes when asked if you have book expenses, in the 1098-T section.
