Thank you. We are submitting the 2023 return with the w-7 for the itin and since our kids and I are US citizens and my wife is getting an itin we would like to file and amend past years. Have not filed 2022 return at all. 2020 I filed head of household and 2021 single even though we were married but didn't know how to file because we did not have itin. For 2020 we got stimulus payments when I filed head of household. For 2021 we got chikd tax credits when I filed single. Can I file 2022 return jointly and claim child tax credits as well as amend 2020-2021 return to add income and also claim child tax credits jointly which would increase the credit? Would they accept it? What is the source whether you can or can not
