I believe it is ADP + pi + energy ------> ATP

Yes, although you wouldn’t write + energy.

energy is needed to make atp tho.

Yes but that would be written as an enthalpy change, you don't write that energy is needed for any other reaction just like you don't need it for phosphorylation

For this one:
eduqation showing formation and breakdown of ATP

Do i need to put + free energy? Or just leave it as ATP+H2O→ADP+Pi

True, but as chris01928 has said, that would be written as the change in free energy (not enthalpy).

Energy is not a reactant.

Strictly speaking, it would be written as change in Gibbs free energy, not enthalpy. The formation of ATP from ADP is actually exothermic, however, the reaction actually uses free energy.

Leave out the energy, energy is not a reactant.

Ofc how could I forget ahout free energy. My mistake!
