I receive s.s.d.i benefits via direct express on a debit card, how do I convey that info to turbo tax?

You will get a SSA-1099 form with that income which you report on Turbo. 

Social Security mails you a tax document called a SSA1099 in January.   You will enter that into your tax return.   If your ONLY income is Social Security, you do not need to file a tax return unless you have a 1095A for marketplace health insurance.

 Go to Federal> Wages & Income>>Retirement Plans and Social Security  (SSA1099 and 1099RRB) to enter your SSA1099.
