@Ulug670873 , agreeing with answers from my colleagues @xmasbaby0 and @AmeliesUncle , in addition to :
(a) when did you enter the US with F-1; was this your first visit or were you here with another visa earlier;
we still need to know :
(b) where are you from -- this is because for some countries ( India for example ) US - other country tax treaty dictates treatment of various deductions.
Your question about "extention request " really is not as important as filing your return as quickly as possible -- I say this because all it assures you is that the penalty for not filing ( if ) would be waived -- but it is rarely applied un less one is habitually ignoring the laws and requirements thereof.
Is there more one of us can do for you ?
