On 1099-r its telling me that the zip code I've entered for owings mill, md 21117 is incorrect. i looked it up on google and it is correct. why won't this thing take it?

I entered into my test return and it did not error.  Might try deleting the 1099R and re-entering.  Also found the zip 21133.  The form 1099r is used for reporting distributions from retirement plans.  Depending on the code in box 7, these distributions can be taxable, partially taxable, or non-taxable.  If this was a Covid related distribution, the 8915-E will be used for penalty relief from early retirement plan distributions and include the option to spread the distribution income over 3 years.  This may be a good option if the distribution is pushing you into a higher marginal tax bracket.  You may end up paying less tax if you spread the distribution over the 3 years.
