When you are filing a Joint return there will be 2 columns to enter Social Security. One for each of you. If it doesn't show 2 columns then go back to My Info or Personal and edit the primary spouse to make sure you checked married and filing together.
Enter a SSA-1099, SSA-1099-SM or RRB-1099 under
Federal Taxes (Personal for Home&Business)
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
