I accidentally marked "someone can claim" me as a dependent but no one did.

I accidentally marked "someone can claim" me as a dependent because I thought my mom would but I made too much in 2019 and she didn't end up claiming me. I'm going to send in an amendment to correct this error but I'm wondering if this will affect my right to a stimulus check for COVID-19. Will I be considered a dependent even though no one ended up claiming me? Thanks in advance.
