"Turbo tax is not telling me to mail W-2's to Kansas with my mail-in return. Do I?"

Yes, if you are mailing your state tax return, attach the W-2's to the return. 

Thanks for the clarification and quick response.

You are welcome! 🙂

What about including a copy of your Federal Return with your Kansas Return?  Does Kansas still require that?  TurboTax instructions do not say?

@sandyharder  @maamsmith  The following is from your State.

Mailing your return: Before mailing your income tax return, be sure you have:

• completed all required information on the return;
• written your numbers legibly in the spaces provided;
• enclosed, but not attached, all K-19 forms;
• enclosed Schedule S if you have a modification on line 2, if you filed as a nonresident or part-year resident, or if you itemized your deductions for Kansas;
• enclosed Form K-40V if you are making a tax payment; and,
• signed your return.

NOTE: If your K-40 is filed with a Kansas address, do not include a copy of your federal return; however, keep a copy of it in case KDOR requests it at a later date. If your K-40 shows an address other than Kansas, you must enclose a copy of your federal return (1040EZ, 1040A or 1040 and applicable Schedules A-F).

Yes, you need to include a copy of Federal with your state return.

@sandyharder  My answer above shows what you need to include with your Kansas tax return.  You DO NOT include a copy of your Federal return if you filed with a Kansas address.  Only include your Federal return if you do not have a Kansas mailing address on your return.

If your K-40 is filed with a Kansas address, do not include a copy of your federal return; however, keep a copy of it in case KDOR requests it at a later date. If your K-40 shows an address other than Kansas, you must enclose a copy of your federal return (1040EZ, 1040A or 1040 and applicable Schedules A-F).

Actually it doesn't seem it was required to send them.
This is from the instructions straight from Kansas Department of Revenue:

"The Department of Revenue does not
require that you enclose copies of W-2s or 1099s with Form K-40,
but reserves the right to request them at a later date."

Instructions can be found here 

Once you have the instructions for the tax year you need.

You can press Ctrl + F on your keyboard and search "W-2".
