@rjsThanks for the answer!

 

More questions:

 

1) I want to pay online, because I can be ensure that the value is paid. But if the return is started to process, will they know that the money that I owe is paid?

 

2) Also, should I sent the CARES Act money back if they have not processed my return yet? And should I sent it as the check (the method you have provided above)?

 

3) May I have the problems if

a) I have not provided the incomes properly in my previous 1040 in the case if they have not processed my return yet (I know that the system can check some returns) ;

b) I don't sent the CARES Act money back? ;

 

4) How much should I pay in this moment if the owe is 332$ ? I am the individual.

 

And additionally (offtopic): If the mail is wrong, is it sent back to the sent address in the USA?
