Hi, I'm Robert. Welcome to JustAnswer. I'm reviewing your question now and will post back with your reply momentarily.
Most likely the piping between the bottom of the toilet and tank is clogged, few options you can try, first is a spray wand most RV stores sell them and this would allow you to run the wand so it goes down into the piping and spray it out. Shut the water off first so the toilet does not fill when you are spraying.
The other option is to get an old garden hose and sprayer and do the same thing, run the hose do it goes down into the pipe and give short burst of water while moving the hose around, that will normally clear any blockage.
