I had to pay a federal tax last year and this year. Will my state refund direct deposit info link to the stimulus check deposit?

No, the state refund information is not used by the IRS.

If you have filed a 2019 tax return and need to change or add your direct deposit information, see this IRS website - https://www.irs.gov/newsroom/economic-impact-payments-what-you-need-to-know
The IRS does not have my direct deposit information. What can I do?
In the coming weeks, Treasury plans to develop a web-based portal for individuals to provide their banking information to the IRS online, so that individuals can receive payments immediately as opposed to checks in the mail.

If your federal form 1040 shows direct deposit information on it near the signature line and that information is still correct, you don't need to do anything. The information would also be at the top of the filing instructions form. If there is no direct deposit information on your tax return, you will need to enter that information into an IRS online portal that will be opened soon. See this web site to track it's availability: https://www.irs.gov/newsroom/economic-impact-payments-what-you-need-to-know

It's possible my assumption at the top of this post may be incorrect. You should go ahead and enter your direct deposit information in the IRS portal when it becomes available.
