i had prepared the amendment for my 2019 tax return with Turbo Tax online, and submitted a paper 1040X and sent via mail to IRS in July 2020. I am yet to get an update from IRS or even an acknowledgement. when i enquire on their hotline, i get a standard response that 'there is no update available'. i am wondering if i can use Turbo Tax online and efile the same 1040x for 2019. if not possible, should i sent the paper 1040x by mail again to IRS?
