Contact the payer to obtain a corrected Form 1099-R.
A code H Form 1099-R reports a rollover from a designated Roth account in the qualified plan like a 401(k) at her old employer to a Roth IRA, not to an employer-provided plan, and must NEVER have the IRA/SEP/SIMPLE box marked; it's the improper marking of the IRA/SEP/SIMPLE box on the code H Form 1099-R that is causing TurboTax to treat this as taxable. Direct rollovers from a designated Roth account in an qualified retirement plan to a designated Roth account in another employer-provided retirement plan are to be reported with codes B and G together (an no marking of the IRA/SEP/SIMPLE box); no other type of rollover of Roth funds between employer plans is permitted.
