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.

Turbo Tan form does not provide Box 3 to enter the info provide by SSA. Help!!!

Box 5 is equal to the amount in Box 3 minus the amount in Box 4.

So in the normal case (i.e., box 5 is a positive value), that's all you need to enter (well, that and box 6). 

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

Social Security is on 1040 line 5a and the taxable amount on 5b.

To see the Social Security Benefits Calculation Worksheet  in Turbo Tax Online version you would have to save your return with all the worksheets to your computer.  Or if you are using the Desktop program you can switch to Forms Mode (click Forms in the upper right) and click on SS in the list on the left side.

When i try to enter the information in the boxes a blue dot appears and the form will not accept the information.

what can i do to override this blue dot business?

If you are using Turbo Tax Online, the most likely reason for buttons that don't work or not being able to enter information is that something in the web browser is not displaying the page properly.

One way around this is to simply use a different web browser.  You can select from Google Chrome, Mozilla Firefox, Internet Explorer or Safari.  

OR, try closing TurboTax, clear your Cache and Cookies and revisit the 1099-SSA entry page.
