This was asked in a similar question but the answer was that TT does not have this functionality. This is a key piece of the latest tax code and I decided to use it. Does Intuit monitor these questions? It seems that someone should be able to answer this question and suggest an alternative if they do not plan to address it.
As you said, from what I have read TurboTax does not support that, so you will need to use another method to file your tax return. If I remember correct, the Moderators have specifically said they will not be supporting it this year.
I thought this was a comment from some one that is a part of the community and said it currently does not function. I did not hear that Intuit/Turbotax had no plans to support it in 2018. I will need to file an extension anyway so better late than never. It is disappointing to me that I purchased a product that I can not use. Does anyone know if Intuit answers questions on this forum or if not how else can I contsct them to get this confirmed?
use a different Code (like B) to get your adjustment amount on form 8949 and calculate your tax
Then get the fillable-PDF version of 8949 from www.irs.gov
OR
use Wite-Out and enter the correct Code.
You'll have to file a paper return via US Mail.
