Can I transfer info from a 2014 or earlier return into TurboTax 2016?
No. You can only transfer from last year's return (that is, your 2015 return).
We don't let you skip years because omitting the previous year's information is likely to cause problems.
These can range from relatively minor ones like e-file rejections due to incorrect adjusted gross income (AGI) info to major ones like the inability to calculate state income tax refunds, depreciation, carryovers, and other crucial items that build upon amounts from the prior-year return.
