Do bank transaction histories count as records for purchases made that might be subject to North Carolina consumer use tax?

I had made out-of-country purchases during the 2020 tax year that I didn't pay North Carolina sales tax on. I have no receipts for any of them except for one. I assumed that bank transaction histories wouldn't count as a record of purchase.

I filed my 2020 North Carolina state tax return already, but now I'm anxious if I made some wrong assumptions.
