The IRS method uses the ratio of days rented divided by the total days used (rental days + personal days) ,while the tax court method uses uses the ratio of days rented divided by the number of days in the year.
If you have put a number in personal use days, try removing it to see if it will allow you to use the Tax Court method. You also might going to the Forms Mode and select Schedule E worksheet to manually adjust the days rented vs. personal use. This might bypass the issue with the automatic method selection.
