Hello,
For the 2020 year, I'm not able to locate where to enter the total cost spent on business materials purchased.
I run a masonry business, the materials are things like stone, cement, wood.
Last year I entered it under the following:
How much did you purchase during the year?
Enter how much you paid for goods used for resale or in manufacturing, minus any discounts you received. Include what you paid for freight and delivery. Do not include the cost of goods you ended up using for personal purposes.
