Do I need to pay estimated tax or can I use safe harbor?

Last year I had very low total income. My 1040 line 24 total tax was only about $1500. This year I have much higher income. About half of my income this year is ordinary, and the other half is short term capital gains.

As far as I understand it, I don't have to prepay more than 110% of last year's tax which would be 1650? My job withholdings are more than this already.

Does this mean I can ignore figuring out estimated quarterly payments on my capital gains and just pay tax on that with my annual filing?

Thanks!
