01 Honda Accord brake light and tcs light on

My Girldfriend has a 01 Honda Accord and said the brake light and tcs light are both on in her car. The brakes are going almost to the floor and she can barely stop. She is also having acceleration issues almost like its bogging down when she is accelerating. I drove it and it was getting to 4k RPM and then shifting hard into second. This didn’t start until her lights came on. I put what brake fluid i had in my garage into the car because it was low and i got it over the min mark. At that time the lights went off but 1 day later and here we are. Any ideas what could be going on or any common issues that I could test out to narrow down what might be happening?
