@weirdbaldguy If you have already verified that your TurboTax software is up to date by clicking on Online and then on Check for Updates and the 8936 is still not available or calculating incorrectly then try a manual update.
See this TurboTax support FAQ for manually updating the software to R18 using a Windows based PC - https://ttlc.intuit.com/community/updating/help/manually-update-turbotax-for-windows-software-basic-...
