Has anybody got a solution yet in TurboTax Premium to file IRS form 8833 for the Tax Treaty? Why cant TurboTax let us attach it to electronic return and file it?

Form 8833 Tax Treaty I can enter the amount in TT as other income, but then am not able to file the form 8833 and ultimately e-file if I use TT. Surely TT Premium should offer this. Apparently one of their contenders does!
