how do I find out if my daughter, who's 13, has an IP PIN? I have full permanent custody for the last 14 months. her mom might be trying to have someone else claim her?

I got a notice when I filed my taxes that the qualifying dependents IP pin doesn't match, I didn't put any IP pins on my taxes except for my own. could my daughters mom be trying to prevent me from being able to claim her on my taxes by requesting an IP pin so that she can have someone else claim my daughter? Due to whatever legal reasons my ex isn't able to file taxes on her own. so she would have to have someone else file.

The IP Pin will change each and every year. This is an Identity Protection Pin. Try the retrieve IP Pin link below. 

You can get an Identity Protection pin here, or if you lost your IP PIN, you can go here to Retrieve IP PIN. 

Here's how you can fix a reject: 

Sign in to your account and select the Fix my return button. Follow any “fix it” instructions to update the information causing the rejection. 

Note: Not all rejections will have explicit guides to fix the information. You’ll need to navigate to the program area to address the cause of the rejection. 

Time-saving Tip: If what you originally entered is correct, you won't be able to e-file. There's probably a data mismatch at the government, a dependent that's already been claimed, or some other situation beyond your control that prevents your return from being e-filed. In this case, your only option would be to print and mail in your return. This article will give you instruction on how to print and mail your return.
