That could be right. You had 22.5k of income (not including ss). Looks like only a little of your ss is taxable. Your Standard Deduction is 28,700 leaving you a small taxable income. Is the 4K your AGI or taxable income?
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
