I've not heard of returns being held up for this reason, but the best way to check the status of your return/refund is at the IRS Where's My Refund? site.
If you entered the info from the 1095-A for your child on your return, this should be sufficient for the IRS to process your return. There has been some delay with returns claiming the Earned Income Credit, or Additional Child Tax Credit, if that applies to your return, but they are in the process of being released now.
Here's more info on Why is My Refund Delayed?
