Does having more than $500 in non-cash charitable contributions increase audit risk?

We moved last year and made 20 donation trips to charities.  I'm still working on the valuation but even with my pretty low estimates I am at $1k.  Does this increase audit risk?  I have receipts, but they are just generic, we have to fill in what it was of course.  I have photos of some of it but not all. 

 

It's Deductible seems to value things a lot higher that I would (plus it's a bit cumbersome), so I haven't used it in years past and just stuck to under $500.
