I WASN'T trying to send in the Form 1310 with the tax return. The glitch has nothing to do with this. It's TurboTax. Read the other posts/comments.
For what it's worth, I'm a CPA so I know a little bit about filing a tax return. The problem is that TurboTax won't let you check the appropriate box, which is "court appointed personal representative."
The relevant/required forms had already been filed and received by the IRS
