Although, I cannot guarantee you will receive your refund, most likely your federal refund will not be affected if it is your 2019 state return that is being audited. The process of the state reviewing your current tax return will generally take some time and it sounds like your federal refund is currently being processed.
However, if you had any outstanding debt (such as past due child support) or a past due federal or state tax liability, your refund would be used to offset that before any amount was paid to you.
If you do not receive your refund, generally the IRS will notify you by mail of any amount that was offset to pay other debt.
