I assume that the form is in your name, not in the name of the decedent. You can enter it as Miscellaneous Income -> Other reportable income. This will place it on Schedule 1 line 8z where it belongs as if it had been properly reported on Form 1099-MISC, but allowing you to provide your own description of the income instead of forcing a description that says that it came from a Form 1099-MISC.
There is still a chance that the IRS will question this income since it was reported on Form 1099-NEC instead of Form 1099-MISC on which it should have been reported.
