What do I do with charitable donations and medical expenses if I know they are going to be less than the standard deduction this year?

We have quite a number of charitable donations about which we're being asked "do these still apply?"  Many of them do, but because of the doubling of the standard deduction (in 2018?) and the fact that a significant amount of our medical spending was through our HSA this year, which it hadn't been previously, I don't think we'll have enough of those + medical expenses to itemize.  Am I supposed to mark them all as "no," even though in another year or two I might need them again and would like them all to stay with our information?   I really, really don't want to take the time to add them all up, especially because I wasn't as meticulous as usual in keeping records, thinking I wouldn't need them for the reasons listed above.  Please help.   What about medical expenses that weren't paid for via our HSA but also won't be enough to itemize?
