Is a 403b considered a type of IRA?

It’s not a type of IRA and is similar to a 401-K. 

Why are you asking?  You do not enter 403b contributions under Deductions.  Only enter it from your W2.  Or did you take a distribution?  

If you received a distribution from any type of employe sponsored retirement plan (includes profit-sharing, 401(k), 403(b) and 457(b) plans) they are not IRA.s but are considered a type of one, Distributions  automatically qualify as RMDs

No, but they both are tax deductible retirement savings plans that grow tax deferred.  

The 403(b) is a Qualified retirement plan. A 403(b) is only available to employees of certain organizations, and it has higher annual contribution limits.  

• The limit on elective salary deferrals - the most an employee can contribute to a 403(b) account out of salary - is $22,500 in 2023 ($20,500 in 2022.
• Employees who are age 50 or over at the end of the calendar year can also make catch-up contributions of $7,500 in 2023, and $6,500 in 2022,
