Do I need an actual 1098 form to itemize mortgage deductions?

Also, do I need a HUD settlement statement for the mortgage, and do we need a written receipt or statement from our daycare operator that we paid out $5000 in daycare?
My wife and I are filing jointly but we are seperated and are divorcing next week, so she is on me about filing but I havent gotten my 1098 yet. I have tried to google these questions and haven’t got the answers I need yet.
Thanks!
