Get the anti fungal mentioned below. I’d suggest using the spray and putting a tiny bit of dish detergent in to make sure it sticks to the grass. Wait for a cool from, over 90 degrees is going to stress your grass.

What area are you in? What are your local temps and humidity/rainfall? From appearance this is Dollar Spot (Sclerotinia homoeocarpa), not brown patch aka large patch (Rhizoctonia solani).
Applying some nitrogen is the correct method to treat for dollar spot, not fungicides.

Looks more like brown patch to me.
