I'm using Intuit Turbotax Deluxe for Mac filing for 2018. The program says I cannot submit my taxes because form 8863 is not available. When will it become available?

I am trying to file my taxes for 2018 using turbotax for Mac. The program is telling me I cannot file because form 8863 is not available. When will this form become available so that I can complete e-filing my taxes?
