My mother board is Asrock B450 Steel Legend. Currently,
M2_1 is utilized by Samsung 970 EVO Plus 250GB PCIe NVMe M.2
M2_2 is utilised by Crucial P1 1TB 3D NAND NVMe PCIe M.2
Graphics Card on PCIE1

I would like to add 1TB SATA SSD to SATA3_A1/A2 or SATA3_1/2

Mother board manual says, https://download.asrock.com/Manual/B450 Steel Legend.pdf
M2_2, SATA3_3 and SATA3_4 share lanes. If either one of them is in use, the others will be disabled.
If M2_1 is occupied, PCIE4 will be disabled.

Will I have any issues adding 1TB SATA SSD?

Thanks.
