Convert T12 to TAX12

It seems that the only feasible way how tax returns from one software can be converted to another type, would be to use some commonly used standard like TXF, or OXF, but direct export (like t12 to tax12 conversion is unlikely. This means that you have to export the original T12 file to one of these formats in At Home program, and then import it to TurboTax where you can save it.
