starter

I have a 2013 Jeep Wrangler Unlimited Sport four-door four-wheel-drive soft top. The other day I came out to start it and I didn’t turn the key far enough forward to get the vehicle started. I then turned the key back off and then try to start it again at that point the starter was just spinning...

95% sure my starter went bad on my 2008 Jk and trying to take it out to get tested. 2 Bolts and nut on wiring came out fine but now the entire starter is glued to its housing and wont budge. Most presumably from rust build up. Any advice how to get it out myself before I take it to a shop?
