My calculation was a mistake need to refile

when you make a mistake (IRS calls it a miscalculation),

IRS computers will correct most common mistakes.

SO,

wait until you see what IRS does with the tax return you filed.

there are many items the IRS will not correct because they will not know they are wrong.  for those you'll need to file an amended return but you'll have to wait until the original return is fully processed.  if you tell us the type of mistake we can give you a good idea of whether to wait for the IRS or wait and file an amended return.
