Well the program doesn't do the allocation automatically anyway so they will need to do some of the math themselves anyway even if they use the sale of business assets section ...
Ok ... a simple example of ratios ... if you have more assets than the example then you will have more lines. Remember if you divide a big number into a littler number you get a % ... thus 5000/100,000 = 5%
original cost basis ratios Sales price cost of sale
home 80000 80% 160,000 8,000
land 15000 15% 30,000 1,500
roof 5000 5% 10,000 500
totals 100,000 100% 200,000 10,000
All you need to enter into the program is the % of sales price & % of cost of sale for each asset ... IGNORE the depreciation taken as it is immaterial for the sales of the assets.
