A taxpayer took a distribution in 2020 and chose to split up the tax over 3 years.  Now for tax year 2021, obviously, there is no 1099-R.  Is there any special indication to tell the IRS that the distribution was made in 2020,but paying one third of the tax this year.  I'm am just thinking ahead, knowing that there will be no 1099-R on the IRS wage and income transcript for 2021.  Am I just putting the distribution in with the  proper ein# and one third of the original distribution
