In some instances, TT only accepts number up to a certain amount. For example, 99,999,999 gross proceeds of revenue was a TT limit a fair number of years back, perhaps still is. However, if you had 99,999,000 in cost basis, the net is only $999, well within TT parameters. The IRS wants you to report $999 taxable net. So Just reduce the proceeds and cost basis by an equal amount to bring revenue below the max, and include a note explaining what you did. IRS will get paid their due, but in such a case, I would append an explanation (TT allows such, I recall) or you can print and iterlineate "*see appendix xxx, attached" (Appendix "xxx" [or whatever] your true numbers, details and reason for doing it that way) and file return manually if TT won't import that information. Or if tax treatment is the same, perhaps just add it into an "Other income" area with explanation. Also, run it by TT or a tax advisor to be sure it wouldn't violate a rule specific to whatever category you are entering. Eg., if you have investments with a foreign brokerage(s) totalling above a certain amount , there is an amount where a special return is required by the IRS. But in many or most cases, my math trick should work. It did for me some years back. Just make full disclosure in your return.
