they put a hold on my taxes

No one here would know, since the IRS does not notify Turbotax.  But "verifying for accuracy" could mean a number of things.  For example, they may not have received a copy of your W-2 from your employer, so cannot verify the wages that you claimed.  Or maybe you claimed an unusual deduction, so someone at the IRS is manually reviewing it. The IRS also pulls a random sampling of returns for manual review.

It's possible that the IRS will send you a letter asking for more information, or some form of proof of something, so keep an eye out.  I 've done pro bono tax work for years, and one of my clients was asked to provide documentation of two of his dependent sons, as both were only 5 years younger than him.  But they were adopted.
