2019 Non Filer Form Mistake

In an effort to make sure that the IRS had my direct deposit information, I filled out the Non-Filer 1040 on the IRS website, not knowing it would be accepted as my 2019 return. (I have to pay taxes every year, so the IRS did not have my direct deposit information).

 

So, when I went to e-file my actual 2019 return, it was rejected because there was already one on file. Is there a way to correct without filing an amended return? If not, when should I file the amended return. 

 

Thanks in advance!
