My three T4As are $5573.51 (OAS), $10,383.30 (CPP) and $7,598.62, for a total of $23,555.43. Turbotax has counted the OAS twice, for a total of $29,128.94

My three T4As are $5573.51 (OAS), $10,383.30 (CPP) and $7,598.62, for a total of $23,555.43.  But on the next page, Total Income Summary, my Pension Income is $29,129.00.Why?  It appears that It has counted my OAS twice.... 

 5573.51+5573.51+10383.30+7598.62=$29,128.94

Do not enter all these amounts on the T4A entry pages.
OAS must be entered on the T4A(OAS) page.
CPP must be entered on the T4A(P) page

It works fine, done it myself. Enter each slip carefully and read instructions.

It did the same thing to me and I entered each amount separately. It doubled the OAS.  I was able to get the correct amount by entering only the Gross Pension Paid (box 19) and leave box 18 blank.  If I tried entering in box 18 only and left 19 blank, it doubled the amount. And it doubled it if both 18 and 19 were entered, which isn't right either - they're not supposed to be added together.  Not a good feature of the software.

And now Turbo tax won't allow me to submit to CRA unless the OAS is counted twice.  It will not accept entry of the OAS in Box 19 only.  In order to get rid of the error message, it forces me to go and enter the OAS in such as way that it double-counts it.  This **bleep**ty software just wasted 2 hours of my time.  Buyer beware.
