FTP on a trainer will probably be higher than your FTP if you measure it on a road somewhere, but if that's the best you got go with it.
Part of the process of developing an FTP is familiarizing yourself with the test, so odds are you will not do it right, or well enough, the first couple times. Don't let that get you down, it's like everything else and a little practice will improve your results. Next time you'll know to go a little harder right from the start. (or easier). It should get to where you are nearly dying at the 20 min. mark if you're doing one of the 20 min. FTP tests.
Make sure your legs are nice and warmed up first.
