How handy are you ? First determine where the leak is- which end. Also, is it a soldered connection leaking or a screw in connection. If screw in you might be able to fix it. If soldered, unless you are familiar with how to do that, then you will need a plumber. If a screw type- turn off water at your main source. Put a bucket below the connection to catch water in the line. Disconnect it and wrap plumber tape to line then screw it back on. Then a bit of plumber putty around it. just to help secure it. Then turn on water and tet the line. If that doesn't do it you will need a plumber.

Time to replace the water line. The rubber seals eventually get compressed and hard. No need for teflon tape or putty. The rubber seals are cone shaped so they seal when tightened. Take the old one with you to the store so you get the proper length or measure the distance from the toilet to the valve. When you install the new one put a coil in it when tightening.

did you replace any washers?

You may need to replace the entire water line.
