<p>Ok, I'm looking at the IDOC cover sheet. My custodial prent only has 1099s to submit, does not need to file taxes. My non-custodial parent will have tax returns, 1040, schedules, etc. So do I check only the "Noncustodial Parent's Statement" and include all of these forms or check the box for each of these forms on the parents part?</p>
