I called 1-800-4-INTUIT ([phone number removed]) and spoke with them and we walked through it.
If you actually go to FORMS in the upper right corner of the TurboTax Desktop App. Then scroll down to the the form 8915-E which is the worksheet. You will see Block 1 FEMA #, you can then delete that entry and then if you look on the next form 8915-F you will see it is deleted. Save your return and re-file it.
I went ahead and just re-filed mine and looked at my forms again and that entry in line C is gone.
