Someone help!!

So I bought this car seat yesterday because it was on sale at Walmart for just $35. My problem is that I now need to purchase a stroller but I’m not sure that I can buy just the stroller that is compatible with this car seat. Everywhere I look online I can only find the travel system but obviously I already have the car seat & the base. Not sure if I should return this and just buy a travel system or if someone can help me find just the stroller that is compatible with this seat!
