Deductions & credits

If I understand correctly, the 8917 for 2018 is unavailable, meaning even if eligible for the deduction in 2018, it was not applied in error?  Does this mean I need to file an amended return once the form is available to get the credit?  My calculations tell me that the IRS owes me $2000.00 from the 2018 return due to this form not being available.  Will Turbotax inform me?

 

Thank you.
