If it’s asking for the EIN you are in the wrong place. You don’t enter Social Security SSA-1099 under 1099R. It has its own place. So delete it and enter it here…..
Enter a SSA-1099, SSA-1099-SM or RRB-1099 under
Federal Taxes on the left side or top
Wages and Income
Then scroll down to Retirement Plans and Social Security
Then the second line - Social Security (SSA-1099. RRB-1099) - click the Start or Revisit button
