Regarding royalty income, can we add what the company has taken from the gross income to our expenses?

The 1099-MISC has only 1 box filled in, that for royalties (2). Above the actual form they have typed in 2 figures, one labelled "Other Deductions" and another labelled "Production Taxes." Together these 2 amounts are about 30% of the royalties. Are we allowed to add those amounts to our expenses?
