Federal tax return showing as 'not signed' in college financial aid portal

Thanks! Will IDOC ‘know’ what to do if I delete the 1040 I’ve got uploaded, and which they sent to the schools, and upload a replacement? The 1040 no longer shows on my ‘to do’ list there.

A couple other of my daughter’s schools show the 1040 as received and ‘signed’, so there does appear to be variation in how this is handled.
