The Alabama forms show that they will be released by TurboTax tomorrow (2/28/2019).
If you are an online user, the forms will be updated automatically when the release happens (no, I do not know what time of day). If you have the desktop software, you will have to check for updates (click on Options at the top, then click on Check for Updates).
Please keep track of the release date at https://ttlc.intuit.com/replies/3319879
