The state of Indiana does not tax Social Security benefits. Indiana may tax certain other kinds of retirement income. Did you enter your SSA1099 in the wrong place in the software so that it was treated as some other kind of income?
Go to Federal> Wages & Income>>Retirement Plans and Social Security (SSA1099 and 1099RRB) to enter your SSA1099.
If you entered your SSA1099 in the correct spot in the federal software, it shows up on your Form 1040 on lines 6a and 6b.
States that tax Social Security benefits:
CO, CT, KS, MN, MO, MT, NE, NM, RI, UT, VT,
