You will NOT report anything for this on your 2018 tax return. Not one penny. But do keep all your receipts and other paperwork. Startup expenses are claimed in the first year you are "open for business", and it does not matter what year those startup expenses were incurred. So since you were not "open for business" on or before Dec 31, 2018 you have *nothing* to report concerning this, on your 2018 tax return. Not one penny. You'll deal with it on your 2019 tax return when you file it next year. *KEEP* *YOUR* *RECEIPTS*.
