After you file

This was a user entry error ... if you did not understand the question you should have clicked on the LEARN MORE  link to be educated ... the program cannot answer these questions for you ... all a DIY program can do is ask them.  

To correct this you can mail in an amended return to "claim yourself" which will take 16 weeks or more to process which may generate a stimulus check this year  OR   you can get it when you file the 2020 return next January.
