You should have filed a non-resident return for Missouri. Did you follow the following steps for filing in MO?

1. With your return open, select My Info in the left-hand menu.
2. Then, on the Personal info summary screen, scroll down to Other State Income, and select Edit.
3. At the Did you make money in any other states? question, answer Yes and make sure your nonresident state(s) are selected from the drop-down.
4. Select Continue to return to your Personal info summary.

After you finish your federal return, you'll automatically move to the State tab, where you'll see your nonresident state(s) listed in addition to your resident state.

Tip: To ensure accurate calculations, always complete the non-resident return first if filing in multiple states because your resident state might give you a credit for any taxes paid in that situation.

I really appreciate this feedback! This is very helpful.

Unfortunately, I did not do this. I do not remember going through that step. As always, I followed all the steps given to me from the beginning. When completing my KS return, it did ask the questions of if I made income from sources outside the state, which is where I entered my MO income and tax info and where I then received my credit.

Do you think I will be successful in now adding a filing for MO on Turbotax, even though I did my resident state first?

Actually I think I just figured it out! I was able to still go back and add my MO filing. Than you so much for your help and time!

You are welcome!
