Filing Late

So last year I had student loans in default and after last years tax season I didn’t get a refund, turns out it was due to me not submitting the right forms not because of offset but im certain they would have been, since then though my accounts are in good standing and I am actively out of default, so I filed this year and last years taxes, this year wer not offset I was wondering if last years will be offset or if that money is just gone due to late filing ?
