We received FormSSA-1099-Social Security Benefit Statement. Where do we input this info?

To enter your Social Security benefits reported on form SSA-1099

• Click on Federal Taxes
• Click on Wages and Income
• Click on I'll choose what I work on
• Scroll down to Retirement Plans and Social Security
• On Social Security (SSA-1099, RRB-1099), click the start or update button

Then depending on other income on the return TurboTax will compute if any of the Social Security is taxable income. 

I got a social security form SSA-1099

Did you even read the answers already given in this thread that tell you where to enter a SSA1099? Do not try to enter your SSA1099 or RR1099RB as a W-2. Go to Federal> Wages & Income>>Retirement Plans and Social Security (SSA1099 and 1099RRB) to enter your SSA1099.

My software doesn't allow keyboard input into the turbotax form 1099-SSA. This makes the software useless for filing,

What?  Is your number key locked?   What else are you having trouble entering?

Try using a different internet browser.

Any chance you are using the "Desktop" software?

IF so, try double-clicking in the field first  (especially if you see a "$0" there).  You might have a "Supporting Details" worksheet associated with that field.
