Get your taxes done using TurboTax

My wife and I always file jointly and last year (2021) made over the cutoff for the third stimulus, so we only received a very reduced amount.  I want to file married separately as my wife makes under the single cutoff of 75k so she can receive the balance of her $1400 (minus $365 for her half).  I know that my half that I received last year I would not have gotten on my own as I make over the cutoff for any payment.  Should I not do this?  There aren't any other deductions that we claim.
