SSDI lump sum backpay with a 10 year old onset date (I was awarded monies back before 2014)

I have fought with SSDI (disability) for 10 years and was awarded in 2022 with an onset date of 2014. The 1099 from SSA shows an accurate amount paid out for 2018,19,20,&21 if indeed I was paid out during those years the proper amount we will round up to $12k per year. of what would have been paid out had I been receiving the money. 
Because it’s a lump sum payout they have paid me going back to

my onset date of 2014. However the year of 2022 has an amount of around $30k in addition to the 4 years previously mentioned. The years of 2014-2022 should be spread over 12k per year going back to 2014 IMO but they are trying to tax the lump sum…of course I am trying to spread out the amount accrued over each year which would make it untaxable. 
It’s below poverty line and we are talking about money I have paid in my whole life as a working adult. And because the IRS doesn’t make it easy to spread the money back to

the onset date (12k for 8 years prior to 2023) they want to

tax the money? Seems ridiculous at best considering it wasn’t me dragging the hearings out but SSA(SSI/SSDI). 

Is there a way to spread said monies out over the course of those years I was awarded for? (I filed no taxes save for one year of $0 to get covid relief). I was told to use 1077 but to be frank how they have this lump sum already spread over 4 years then a lump of 30k for 2022 seems like they just want to tax that 30k. Is there any way around this and can someone kindly direct me in the best route to take—I’d be eternally grateful. Thank you.
