Hola Christina
In the hint for that sentence we wrote "use El Presente" to help you remember this structure that we use when talking about things that we have been doing for a certain amount of time - the structure used in Spanish is different to the one used in English. This is why we have specific lesson on this. The lesson Marsha is referring to is this one, have a look. 
I hope it helps.

Answer

Have a look at the lesson: Using desde (hace) with El Presente instead of El Pretérito Perfecto to express since/for.
