It's likely your plan failed non discrimination testing and you are considered a highly compensated employee ($155k/yr for 2024 look back), so you are limited on what you can contribute due to lower earners not participating/contributing.
If the above is correct, and you are a highly compensated employee, you cannot make a deductible Traditional IRA contribution. Depending on earned income levels and what type of health plan you have, options include: contributing to a Roth IRA (not an option if income is above 165k single/246k married filing jointly), making a non deductible contribution to a traditional IRA, then immediately transferring to a Roth IRA (known as a backdoor Roth, if you have a pretax IRA balance this becomes much less attractive), contributing to an HSA if you have a high deductible health plan. If none of those are options, saving money in a regular taxable account, or maybe looking a a deferred variable annuity could make sense.
