Deductions & credits

Hey, I'm in a situation as well. 

This year, I accidentally filed as a independent, (my first year filing taxes), though I am usually a dependent. I recently got my refund, and was looking to file an amended return. However, I received the stimulus check, and I have not yet made motions for the amended return. Is it still necessary to do so? Are there any potential consequences since I recieved the check? I am 18 and so it is obvious that college students are typically not eligible as dependents. In 2020 though, I plan to file as a dependent. Will I have to pay the money back, or have problems with my tax credit for next year? My income is way below the limit for dependents, and will most likely be the same next year.
