Retirement tax questions

I had excess contributions for 2018, 2019 and 2020 which were all removed in 2020 as follows: 

2019 contributions - 4/29/2020 - 7559.20 (559.00 earnings)

2018 contributions -  6/15/2020 - 6500.00 (original contribution - excess was 6060.00 and I realize that after I removed it)

2020 contributions - 12/11/2020 - 2887.76 (733.79 earnings)

 

In 2020:

a) I filed 2018 1040X in 2020 prior to the extended tax deadline to pay the 6% tax

b) I filed substitute 1099-R with 2020 return for 2019 excess contribution removed in 2020.

c) I filed 5329 with 2019 return for 10% penalty on 2019 earnings and 6% tax on 2018 earnings

 

I received a 2020 1099-R listing each of the contribution removals listed above.

 

I have added the 2020 withdrawal on a 1099-R in 2020 return

 

Questions:

  1. How do I report 2018 excess contribution removal in 2020.  If I enter a 1099-R for 2018 separate from the 2020 removal, TT taxes me - why is that - it doesn’t ask me what year the withdrawal was.
  2. On Form 5329 for 2020 - are the following amounts correct?
    1. line 18 shows 6060 (the amount of excess),
    2. line 19 shows 7000 (assuming because I didn’t make any contributions for 2020).
    3. Line 20 is blank (shouldn’t this be 6500, the amount I withdrew in 2020)
    4. Line 22, 24 and 25 show zero
  3. Do I need to report anything else on 2020 return for 2019 contribution withdrawal.
