This FAQ explains how TT handles CA Form 593 and how to enter the form: https://ttlc.intuit.com/questions/2757572-how-do-i-enter-ca-form-593-real-estate-withholding
CA Form 593 shows CA real estate tax withholding; it does not show income. https://www.ftb.ca.gov/forms/2018/18_593.pdf
You would not enter withheld CA tax on a CO return.
If you're a CO resident with a taxable capital gain on property located in CA, the gain would be taxable by both states, but you'd be able to take a credit on your CO return for taxes paid to CA.
Don't know if this answers your question.
