Amending cryptocurrency taxes for the years 2017, 2018, and 2019

Hello,

I want to amend my 2017, 2018, and 2019 taxes. I already have the forms Schedule D and 8949 filled up and I know my capital gains and losses. I'm not very sure what I should do next. Do I need to fill form 1040X for each year and attach the corresponding forms Schedule D and 8949 and then mail each year separately to the IRS? In case I owe the IRS, do I need to include a money order? if so paid to whom?
