I wonder why TurboTax does not make this situation easier by creating 3 boxes, one for 1099B cost base, one for W-2 Box 12a amount "V" for non-qualified stock option exercise gain, and one for the overall cost base (i.e., 1099B cost base + W-2 Box 12a amount) so that it is clear for the IRS.
Are you recommending me to send Form 8453 along with the 1099B and check the following box on Form 8453?
"Form 8949, Sales and Other Dispositions of Capital Assets (or a statement with the same information), if you elect not to report your transactions electronically on Form 8949"?
Should I also write, please refer to company X W2 Box 12a "V" NQ stock option exercise amount, this amounts is added to the cost base shown in 1099B?
