@richlux The Schedule 1-A has been available in TurboTax for two months or longer. You need to make sure you have the latest software update. Click on Online at the top of the desktop program screen. Click on Check for Updates.
If you show as being updated and still have this issue, then use a manual update if you are using a Windows based computer. See this for a manual update - https://ttlc.intuit.com/turbotax-support/en-us/help-article/update-products/manually-update-turbotax...
Or, save the tax return, close the TurboTax program. Close and re-start your computer.
