I would eat at TDEE for your goal, but I think you've underestimated your TDEE, unless you are VERY sedentary the rest of the time? And by very I mean you sit or lie down almost the entire rest of your hours?

I'd call you very active and use the Very active = BMR X 1.725 modifier, for 2314/day.

Are you new to logging? And how long have you been doing sl? What I'd suggest is that you log very closely, including how many tablespoons of milk in your coffee and any condiments you use a fair bit of or that have a fair bit of calories (ketchup is one that people tend to forget, some mustards actually have a bit of calories, etc).

You don't have to be super restrictive, don't worry about going a few hundred above or below if your eating patterns naturally fall out that way, but just make sure you keep good careful track of everything for now and that it all averages to more or less 2300/day.

Then, just see what happens. Keep track of your weight on any schedule you like, provided it won't freak you out. (daily/weekly/whatever).

If you lose/gain over 8 weeks, I'd adjust cals by an appropriate amount in the appropriate direction.

Also, all the above assumes you are not at a very low weight for your height - if you're in the low end of the BMI scale, I'd think about a very small bulk later, plan to gain a few pounds of muscle, but either way its hard to develop a plan to slow bulk unless you're very confident of what you maintain at.

as I've been on the "no more than 1500 cals per day" wagon for quite a few years

Oh dear!

Yes, 1800 cals plus for heavy lifting, you won't gain any muscle or even strength otherwise (you will plateau strengthwise more rapidly on less cals for certain) and also you will feel very fatigued on less calories.
