Thank you so much for clearing up quite a few things. I still have just a few more questions. I have already filed my 2020 return. Do I need to amend it if I did not begin receiving income until March? I have not found how to add the schedule C interview. I understand I needed to click on the amend button to upgrade Turbo Tax to the self employed version, yet the only option is to file or amend 2020 taxes. I am unclear how it works filing quarterly. I also a little confused if I needed to claim income received from another country. The way Amazon KDP royalties are set up, I receive income from its international sites if a customer makes a purchase from that marketplace. I am sorry for so many questions. But I really do appreciate the help!
