Sorry, not helpful. This might work if I'm filling out Schedule A manually. TurboTax has no option for creating a single, generalized entry that gets me to that Line 17 like you suggest. It wants me to "fill in a date for each donation" as if there's a series of donations, and it presents a menu of types of donations, none of which are really close to what we're doing here. I think a $400+ donation for "bedding" will raise eyebrows at the IRS.
I went round and round on something similar several years back, and gave up trying to account for some donations and just ate the loss. IMO, this is the biggest weakness in TurboTax. It tries to be too specific, whereas I could simply make single entry as suggested above ("noncash contributions"), and keep all the receipts if challenged.
