Ok that tells me a day any idea what time i read online that returns that were accepted by jan 23rd should have been in on friday the 7th still waiting .... Any idea what time the irs website is updated

Per the IRS their website is updated daily usually at night. Any dates given are estimates. When your tax return is accepted by the IRS you can get a pretty good idea of when you will receive your tax refund from the IRS based on acceptance date in the chart with the article link provided below, but again please remember these are only estimates:  https://www.cpapracticeadvisor.com/tax-compliance/news/21123770/chart-shows-estimated-irs-income-tax-refund-dates-for-2020. Typically it takes about 21 days to receive your refund from the IRS when you e-file and choose direct deposit as your refund choice. Check your refund status here.
