I have a client that already efiled his own federal return using turbo tax for 2020 and 2021, but never filed a state return.  The reason is because he has 4 state returns to do for both years.   Can I efile the state returns with out a federal return being efiled?   I have completed both years and all the states, but don't know if this is possible since the state usually gets sent after they have accepted the federal.   PLEASE HELP!   Thank you in advance for your time and consideration in helping with this important matter.
