Simple answer: No.
But taxes aren't simple.
Social security only becomes taxable
when added to sufficient other income. If you are otherwise required to file a tax
return, you do need to enter it in Turbotax (TT). TT will determine the taxable
portion.
Social security (including SSDI) becomes taxable when your income,
including 1/2 your social security, reaches:
Married Filing Jointly(MFJ): $32,000
Single or head of household: $25,000
Married Filing Separately (MFS) and lived with your spouse at any
time during the tax year: $0
If you file as MFJ (and you should), his SSDI income must be entered onto your joint return and will (most likely) increase your total reportable income. So, it might appear that his SSDI is now being taxed more than it was before being married. But the bigger standard deduction and lower tax rates for MFJ more than make up for that.
You may think that filing MFS might save you money. That's highly unlikely. Before
making a decision to file as MFS, you should run test returns and compare. You

You can use the same tool for comparing MFJ to Single filing status. But, once you are married, Single status is no longer allowed. You must use MFS or MFJ.
