Turbotax doesn't use this information because a determination of whether or not IRC 448 is applicable must be determined by the taxpayer for each of the entities in which he has a stake. It requires a C Corp, partnership with a C Corp partner or a tax shelter (which can be a partnership with no C Corp partner) to use the accrual method of accounting if the entity's average annual gross receipts for a 3 year period ending with the current tax year exceed $25 million.
Certain entities must be aggregated to determine if they in total have gross receipts exceeding this threshold. Certain entities are excludable. Turbotax is not designed to handle the calculations that may be needed (nor probably most pro software).
you may want to take a look at 448 to see if you (actually entities in which you have a stake might be subject to it). if in doubt you may need to consult with a tax pro.
