I have one male veiltail betta living in the top fin 5.5 gallon starter kit. I noticed the filter was to strong for my betta and a baffle with a water bottle wasn't working. How can I slow this Top Fin 10 filter?

I bought a pack of fluval aquarium filter sponge and rubber banded it around the out pour. Works really well and I can move it up or down or more/less current.

Also, I'm scared my betta will be pulled and stuck on the intake if I put sponge on that is it possible?

I just went and bought this today at petsmart for 3$
It's the fluval pre filter sponge , follow the link to see what it looks like. Another Bettafish.com member recommended it to me and it works great

Both things zozoe said! I baffled mine the same way, I bought a wide enough sponge to go all the way across the outflow and in front of the intake, the while width of the front of the filter, and i bought the fluval pre filter sponge for the intake. if you have a petco near you, I saw them on the clearance table yesterday!

Okay I did both sponge things, but my curious betta goes near the filter and gets pushed down (with zozoe's setup), is it okay?

My current pushes my betta around a tiny bit but he doesn't seem to mind and actually appears to enjoy swimming against the current. If your current is so strong that it's still stopping your betta from swimming around freely or if the fish stays hidden in corners I would try to lower the sponge to reduce the current that much more or try the bottle baffling way, the method is shown step by step in that link .
