I show the IRS Form 4562 as "available" on the webpage at https://care-cdn.prodsupportsite.a.intuit.com/forms-availability/turbotax_fed_online_individual.html
Most likely it's because everything was not present in the program at the time you started your return. It's also possible there was a one-time glitch on the import. I see you're using the online version of Premier. The simplest thing to do is to clear the return and start over. This will force you to import from last year's return again. After import, the first thing you do is check that all imported information was in fact, imported.
Do I need to re-enter all of the info to add it back in?
You can. But understand it's not that simple and re-entering it. A fair amount of manual math on your part is necessary in order to get the numbers right without losing the depreciation history on the asset. The simplest way is to simply start over and import all the data again.
