I have an Idaho partnership that sold land in 2020 on an installment sale.  3 partners - all siblings.  Payments over three years, first payments received in 2020.  The two sisters are taking the payments 50/50 in years 1 & 2 and the brother is taking his full 1/3 of the sale in year 3.  We're specially allocating the gain between the partners to follow the way the cash is flowing.  Everything looks good, EXCEPT - we can't get the capital gain pass-through information on the Idaho K-1 to specially allocate.   I've been all through the state special allocations screen and can't find how to change it anywhere.  Any ideas?  Do I just attach a note to the K-1 with the correct amounts?  I don't file the sister's 1040s, so I don't want their preparer to miss it (it's a difference of about $200k just this year).
