Make sure your banking information is correct. If it is not, the IRS will issue out a paper check to the address that you have on file. Now, if a paper check is being distributed it will take up to 21 days from the filing date. Here's a link with a list of number for the IRS to assist you if you need to contact anyone. https://www.irs.gov/help-resources/telephone-assistance
