Filing an 1045 for NOLs

[rtaxc]

Is there a time limit for filing a 1045 to claim NOLs?  I filed some returns with negative AGI and Taxable income, but they were filed very late, past the due date with automatic extension.

You must file Form 1045 within 1 year after the end of the year in which an NOL, unused credit, net section 1256 contracts loss, or claim of right adjustment arose.
