The etrailer Trailer Hitch Receiver # e98837 which fits your 2010 Toyota Sienna uses six M12 - 1.25 x 40 hex bolts to attach the receiver to the frame. This same hitch is confirmed to fit the 2004-2020 model years. It is possible the threaded holes on your frame could have some dirt or corrosion built up inside the threads which is preventing the installation. You can try using a Brush # 814092 with some penetrating oil to clean out the threads, otherwise you may need to get a tap to chase out the threads.
