let me advise from a different perspective

maybe u can put it as TBD (To be discussed)...and during the interview, can tell them frankly you are not sure what amount to put.

sometimes it is ok to be "human", that you are not perfect to know how much the company will pay you for that position

sometimes it is ok to ask them the range of salaries the company will pay for that position

have a little confidence of yourself and think that they are the one who will benefit if you join them rather than vice versa, because u know u r good.

if the "seniors" (those who interviewed u) thinks that they have done a good job squeezing the amount to pay you because you are not sure, then I think they are wrong...and also they should be able to identify real talent rather than trying to pay lesser for "good" people

just my 2.5 sen
