My spouses company did not withhold any taxes and now I am faced with a large tax bill

My spouses company did not with hold federal income taxes and now I am faced with a large tax bill, how can I make installments without IRS penalties and interest ?

I tried contacting the IRS to discuss - they keep transferring me to a number that says go online for tax answers which is why I was calling them directly is because they are not online ... Aaaargh ..
We asked my spouses employer why they did not take out withholding:

"Back in 2020 the government changed the way we got our taxes. Instead of getting big returns they have adjusted the brackets so that we receive more money through out the year. In 2022 the changed the tax brackets to help with inflation, which resulted in people seeing little to no taxes taken out. You can consult a tax account for further explanation or go to the IRS website at IRS.gov. This is nation wide it is not just "
