@SMilton181 --
@RobertB4444 's answer is not correct.
From Colorado Code 39-22-109(b)(i)(A):
A)Telecommuting. A Nonresident employee who telecommutes from a location outside of Colorado is not working in Colorado and the employee's income from such work is not Colorado-source income.

A non-resident of CO can only be taxed by CO on CO-source income.
If Colorado taxes were incorrectly withheld, the taxpayer should file a non-resident CO tax return, allocating zero income to CO, in order to receive a full refund.
The employer of such a taxpayer should not be withholding CO taxes. See this:
"In general, employers are required to withhold Colorado income tax from any compensation paid to an employee who is either of the following:
- a Colorado resident; or
- a nonresident who performed work in Colorado."
