Two W2 from same employer, both have code DD in box 12

[dcg59]

I received two W2 statements from my employer.

One W2 has all the income information in boxes 1-6 and includes information in Box 12 with codes C, E and DD.

The other has no information in box 1-6 but does contain a Box 12 code of "DD" with a different amount.

When I try to file my federal taxes, TurboTax says I have to file by paper because I have a W2 with no information in Box 1 (the second W2). Other sources seem to indicate that I could go an modify the more complete W2 to include the Box 12 DD information from the second W2. However, when I do that, an error is triggered since there are two boxes with "DD".

I suspect that the reason two W2's occur is because the first was for my employment period, and the second was for health care during my retirement period. 

What's the proper resolution? I've already printed out the full return to mail in so may just do that.

Although you received two pages, it sounds like you received just one W-2.  The second page only reports the second box 12 code 'DD'.

I suspect that if you add the two code 'DD' amounts together and enter one box 12 code 'DD', you will be able to pass Review and file electronically.
