The IRS issues refunds, not TurboTax. Unfortunately, this means that we can't say for sure why you haven’t received your refund yet. Since your return has accepted, you can begin to track your refund at the IRS Where's My Refund? site. You'll need your Social Security number or ITIN, filing status, and the exact amount of your refund to check your status. 

A lot of taxpayers are in the same situation as you due to the IRS backlog right now. Although The IRS issues most refunds from e-filed returns in about 21 days, some returns take more time to review. In addition, the IRS is processing millions of returns, as well as stimulus checks, and they are doing everything they can to be as prompt as possible. 

For some taxpayers, PATH Act requirements and other identity-protection safeguards implemented by the IRS may account for longer wait times.

Other things that can delay your refund include, but are not limited to:

• Liens, back taxes, or refund offsets
• Errors, inconsistencies, or missing information
• Identity fraud
• Form 8379, Injured Spouse Allocation, which can take 11-14 weeks to process

Regarding your unemployment, do not amend your return. Per the IRS, an adjustment will be calculated and your refund will be issued to you automatically, if you qualify. 

IRS to recalculate taxes on unemployment benefits; refunds to start in May

If you had unemployment on the return then the IRS will automatically recalculate the return and send the corrected refund ... DO NOT amend for that reason.  https://www.irs.gov/newsroom/irs-to-recalculate-taxes-on-unemployment-benefits-refunds-to-start-in-m...

However, taxpayers would have to file an amended return if they did not originally claim the EITC or other credits but now are eligible because the exclusion changed their income.  Once the IRS sends the original refund and/or the corrected amount  AND  you have a new credit to report ONLY THEN will you amend the return ... don't try to jump the gun as this will only delay things further.
