We paid 11% of our AGI for 2020. We don't itemize any more. Nothing to itemize any more except property taxes and charitable contributions.
Take a look at "bundling" your deductions into alternate years. For example, I paid my 2019 property taxes in Jan 2020, and my 2020 property taxes in Dec 2020 - so I had
twice my annual property taxes to deduct in 2020. (No penalty from the local taxing districts for doing this.) Maybe it will work for you, maybe it won't - but it's worth looking at.
