My adult child didn't qualify as my dependent, but I still have all her info on my return. Do I still need to include her separate 1095A insurance form on my return?

No.  If she is no longer a dependent on your return, you would not enter her 1095-A or her 1098-T on your return.

If you are both on the policy, then you would need to mark that you shared the policy with another taxpayer, as would she.  Then you would allocate the amounts that you both will claim.  You can split the amount however you wish as long as it adds up to 100%. 

If she was the only one on the policy, then you would not need to enter it on your return, she would just enter the entire thing on her return.
