AutoFill Mysteriously Turned Off in 5.2.3.3 Calc

Prior to upgrading to 5.2.3.3, whenever I started to enter a title or description, AutoFill would suggest the completion based on a higher entry in my spreadsheet.

Now that I have 5.2.3.3 working, that feature seems to be missing, or is off. Please help. How does this non-techie get it back?

AutoInput was moved to the Tools menu in 5.2.3.3.

Thank you for the perfect reply. I should have seen it myself.
