filing severa; 1099 r

I have several 1099 r's to file. some have 7 in distribution box, others have G in distribution box and one has 7M in distribution box. Why is turbo tax adding all of them as income.?The total for my 1099r's is twice what it should be, but I have only entered them once.  These are distributed by  Bank of America for John Hancock and then rolled over from Bank of America to TIAA-CREF. Each company issued 1099R's
