Did you enter the SSA-1099? How is it a problem with Turbo Tax? Does it show up on line 6a? It might not be taxable.
Up to 85% of Social Security becomes taxable when all your other income plus 1/2 your social security, reaches:
Married Filing Jointly: $32,000
Single or head of household: $25,000
Married Filing Separately: 0
Do you need to amend to add it? You should not amend until the first return has fully processed and you get the first refund or your tax due payment has cleared.
